Mega Blaziken is overall worse than regular form in PBB. There's no notable threats that can outspeed Blaziken at +1 while the mega doesn't. Mega is mostly for survivability and speed in some cases, while the regular form deals higher damage with Life Orb and can free up slot for other megas. Both are not that different in usefulness, but Mega has an opportunity cost so it's ranked lower.

Conkeldurr is definitely a good mon in the meta. It faces a competition with other fighting types like Blaziken and Marshadow though, but it is more reliable as a switch-in due to its better bulk. I would rate it B due to the competition.
